Until now, scam ico's are still exist and making more projects... for me all I can do is observing their project for months before I invest an amount.. this is not that effective than you thoughts but it will help you to know more the project you want.. promising projects are everywhere. choose the one that it won't regret you at the end.. grow with this, it will help you.
what if when you have observed they have not been a scam, but when ICO is finished they suddenly scam?
this often happens, even though the team looks real.
Wouldn't it be better to choose IEO, because ICO is now very risky, and even the demand is also small, this will increase the likelihood of ICO failing because it is rarely interested in, and ultimately Scam.
